Increase throughput and capacity in SAG mills FLSmidth

Reduce downtime, save on energy costs and increase throughput and capacity in your SAG mill. Products & Services; Company; LoadIQ and ECS/ProcessExpert reduces your mill’s ball-on-liner impacts with up to 45 percent, which prolongs liner life and minimises media degradation.Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.SAG Mill Grinding Circuit Design 911 Metallurgist

Slurry flow in mills: grate-only discharge mechanism (Part-1)

The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.the ball mills. The ball mills currently produce a final grind size of P 80 of 75 microns (µm). Pustynnoye Gold Mine plans to increase the throughput from 2.1 to 2.5 Mt/a and possibly more in future expansions.
